Detailed Solution
Download Solution PDFजनित्र प्रेरित emf Eg = 224 V
टर्मिनल वोल्टेज V = 204 V
क्षेत्र प्रतिरोध Rf = 20 Ω
क्षेत्र धारा \({I_f} = \frac{{204}}{{20}} = 10.2\;A\)
आर्मेचर प्रतिरोध, Ra = 0.05 Ω
आर्मेचर पात = 224 – 204 = 20 V
आर्मेचर धारा \({I_a} = \frac{{20}}{{0.05}} = 400\;A\)
भार-धारा IL = Ia – If = 400 – 10.2 = 389.8 ALast updated on May 28, 2025
